Definitions

  • This invention relates to improved apparatus for safely and efficiently destroying used hypodermic needles.
  • Used hypodermic needles often contain residues of potentially dangerous materials, such as blood carrying HIV, hepatitis B or other infectious diseases. Because the sharp tips of the needles may prick the skin of persons attempting to dispose of them, many devices are available for destroying the needles. Some of such devices utilize incineration apparatus that generate electric currents that destroy the needle, crushing apparatus that grinds and crushes the needle and the syringe housing, or apparatus using a combination of both incineration and crushing. ⁇ For example, U.S. Patent No. 5,076,178 to Kohl, et al. discloses a needle incineration device.
  • the electrodes of an incinerator-type destruction device may be too far apart to allow the needle to close the circuit between the electrodes.
  • constant use of the device may wear down the electrodes, further separating them, or may leave the electrodes coated with the "slag" created during destruction of a needle.
  • current will either not flow or flow only intermittently from the electrodes into the needle, thereby leaving all or parts of the needle intact.
  • the present invention addresses the above problems by providing a portable device that can be used in a variety of locations, may have a self-contained power source, fully destroys needles of various lengths and gauges in one step, and sterilizes and/or prevents escape of pathogens and potential contaminants. Additionally, one embodiment of the present invention provides a simple and inexpensive needle destruction device that is capable of destroying instantly and completely small needles such as those used by dentists or diabetics.
  • the present invention is a portable needle destroying device provided with a power supply such as a replaceable or rechargeable battery, an adjustable dial that is used to set the gap between two electrodes in order to allow needles of varying gauge to be used with the device, and a filter infused with disinfectant that prevents paniculate or airborne pathogens from escaping from the device.
  • the battery may be rechargeable. Instead, however, of connecting directly to one of the electrodes, the battery may couple to an energy storing device such as an inductor, capacitor or thyristor circuit. The storage device is charged by the battery and holds a charge for release when a needle is inserted and creates a short circuit across the gap between the electrodes.
  • the released charge, or arc is powerful enough to destroy small needles completely without requiring the user to insert successively smaller lengths of the needle into the device in order to ensure the needle's destruction.
  • the released charge significantly speeds the destruction of the needle and the battery may also supply power to the electrodes so that complete destruction of larger needles is quickly completed following initial insertion and release of the stored charge.
  • the device accommodates needles of all lengths and gauges by providing a means for adjusting the gap between the electrodes.
  • the adjusting means is controlled by a dial that the user turns to move an adjustable electrode. Turning the dial in one direction decreases the bias of a spring to allow the adjustable electrode to move away from a second electrode and thereby more efficiently accept a larger needle.
  • the power supply may couple to a motor that optionally rotates the second electrode in order to remove the slag produced during destruction of the needle, as is generally shown and described in U.S. Patent No. 5,138,124 to Kirk, et al., which is hereby incorporated in its entirety by this reference.
  • a direct current (“dc”) motor should be used. Because the motor may be actuated when the user slides a needle into the device and thereby electrically connects the adjustable and second electrodes and causes release of the stored charge, a high starting torque motor (like a dc motor) may be used in order to begin immediately rotating the second electrode.
  • the second electrode is a flat plate with at least one slanted edge.
  • a moving or vibrating means couples to the plate for reciprocating the plate back and forth, thus causing the slag to flow down the sides of the plate and effectively cleansing the electrode.
  • the movement or vibration need not result in great displacement of the electrode, although vibrating the electrode at a high frequency, and beveling one edge of the electrode, may assist in dislodging substantially all of the slag.
  • One such vibrating means may be a buzzer circuit, which utilizes a coil to produce a magnetic field that pulls a metallic strip toward the coil.
  • a buzzer circuit which utilizes a coil to produce a magnetic field that pulls a metallic strip toward the coil.
  • the frequency of the buzzer circuit can be adjusted by changing the amount of field produced by the coil or the spring characteristics of the strip).
  • Another moving means may simply be a motor whose shaft rotates and eccentric weight, which causes the motor to vibrate. Mechanically coupling the motor to the electrode translates the vibration into the electrode.
  • the motor may be used to move the electrode
  • its shaft may also couple to a fan that pulls smoke, dust or particle-laden air through a case holding the battery, motor, electrodes and a disposable cartridge.
  • the air is channelled through the disposable cartridge, which is sealed via a gasket to the side of the case in order to prevent smoke, dust or particles from entering the case that surrounds the motor.
  • the air travels through a filter that is impregnated with a disinfectant and loaded into a removable tray t ⁇ allow replacement of the filter or replenishment of the disinfectant.
  • the disinfectant both cleanses contaminates from the air and deodorizes the emissions caused by vaporization of the residues left in the needle.
  • the device comprises a case that encloses a battery that may be coupled to an energy storing circuit, a first electrode and a second electrode. Either of the first or the second electrodes may be provided with the adjusting means adjustor that allows the user to adjust the gap between the first and second electrodes in order to size the gaps for accepting needles of different sizes.
  • the energy storing device may comprise a capacitor, inductor or a thyristor circuit that may couple to the battery, store a charge, and instantly release the stored charge when a needle is inserted through a hole in the case and contacts both electrodes. If the needle is small enough, the released charge normally destroys the entire metallic tip of the needle virtually instantaneously. This embodiment is thus particularly useful for destroying "double-ended" needles that have a first needle portion with a sharpened tip extending outside the syringe body and a second needle portion that extends through a hub and into the body of the syringe.
  • a recharge pack can be provided for use with the battery. LEDs may be used to indicate whether the battery needs a recharge or when the capacitor will be recharged and ready to destroy another needle.
  • the present invention provides a device for safely and efficiently destroying completely a hypodermic needle of virtually any size and preventing the escape of vapor, dust, particles or air-borne emissions upon destruction of the used needle. Apparatus for removing slag from the electrodes is provided, thereby maximizing the performance of the electrodes.

  • FIG. 2A is a side view of one embodiment of the present invention provided with an adjustable and a rotating electrode with the adjustable electrode set for accepting a small needle.

  • FIG. 4 is a schematic diagram of the components of a portable and inexpensive embodiment of the present invention provided with a storage circuit for supplying a large, almost instantaneous discharge to destroy small needles.
  • FIG. 1 shows in a schematic block diagram one embodiment of the portable needle destruction device 10 of the present invention.
  • a case 11 encloses a power supply such as a battery 12 that couples to a control board 14 that includes a timer 15.
  • a recharging outlet 16 may be provided to allow the device 10 to be plugged into a recharging device in order to replenish the battery 12.
  • Power lines 18 lead from the control board 14 to a charge or energy storage circuit 20 and then to a motor 22.
  • Storage circuit 20 typically consists of a capacitor, although other devices such as an inductor or a thyristor circuit may also be used.
  • LEDs 13 may also be provided on the outside of the case to indicate to the user whether the battery 12 needs to be recharged or whether the storage circuit 20 has recharged and the device 10 is thus ready to accept and destroy another needle.
  • Motor 22 drives a motor shaft 24 that rotates a first pulley wheel 26 and a paddle-wheel fan 32 that has a number of slats 34.
  • An o-ring belt 30 couples the first pulley wheel 26 to a second pulley wheel 28, which in turn drives an electrode shaft 40.
  • Forming the first and second pulley wheels 26 and 28 from a plastics material, such as phenolic, and using an o- ring belt 30 ensures that if a user jams a needle 70 into the device 10, the pulley wheels 26 and 28 will stop while the motor 22 overload initiates.
  • a rotating electrode 44 At the end of the electrode shaft 40 is a rotating electrode 44. Power is transferred to the rotating electrode 44 via brush 42 that couple the power lines 18 to the conductive electrode shaft 40. Although the brush 42 could abut the end of the electrode shaft 40, placing the brush 42 on the side of the electrode shaft 40 ensures better power transfer. Alternatively, the brush 42 could couple directly to the rotating electrode 44, with a channel separating the brush 42 from the end of the rotating electrode 44 to prevent needle residue from interfering with the power transfer accomplished by the brush 42. An adjustable electrode 46 is separated from the rotating electrode 44 by a gap 52, as can perhaps best be seen in FIGS. 2 A and 2B.
  • a gap adjusting means 54 allows the user to turn a dial 56 and adjust the gap 52 between the rotating electrode 44 and the adjustable electrode 46, which is biased by a spring 60 to bear against a fulcrum 62.
  • a spring-loaded set screw 64 is used to set the initial size of the gap 52. Rotating the dial 56 causes it to go up or down a threaded screw 58; the end 57 of the dial 56 thus is moved toward or away from the adjustable electrode 46. Because the spring 60 biases the other end of the adjustable electrode 46 upwards, moving the dial 56 moves the end 57 up or down, causing the adjustable electrode 46 to pivot toward nor away from the rotating electrode 44.
  • Adjustable electrode 46 defines a bevel 48 that ends in a tip 50 for concentrating electric potential and delivering the current into a metallic needle tip 71 once the needle tip 71 is inserted through an opening 68 in the case 11 and contacts both the adjustable and rotating electrodes 46 and 44.
  • a guide 74 is provided that may be generally funnel shaped and spring-loaded with a spring wrapped around flexible portions that open farther depending on the size of the needle 70 being inserted into the opening 68.
  • Guide 74 ensures that the needle tip 71 is brought directly to the gap 52 for destruction. Thus, the guide 74 eliminates the need to "rock" back and forth the needle tip 71 do in order to achieve contact between the needle tip 71 and the electrodes. Guide 74 also hides sparks created during the destruction process from the user and decreases the possibility that waste created during destruction will be thrown through the opening 68 and possibly onto the user's hands.
  • ⁇ Contact of the needle tip 71 with the electrodes essentially closes an open circuit consisting of the electrodes in parallel with the storage circuit 20 and the battery 12. Closing the circuit causes the storage circuit 20 immediately to discharge and create an arc across the electrodes that destroys the needle tip 71. About six (6) volts from the battery 12 has been found sufficient to destroy most needles 70, particularly since the storage circuit 20 initially greatly multiplies the effective current transfer through the electrodes into the needle 70.
  • Fan 32 pulls air through the opening 68 and into the cartridge 80.
  • the air is laden with the emissions from the destruction of the needle tip 71 and is channeled into a filter 82, which is impregnated with a strong disinfectant both to sterilize any pathogens that may have been in the needle tip 71 and not destroyed, and to freshen the air.
  • Filter 82 may be formed of multiple membranes that better trap particles of varying sizes. In order to allow replenishment of the disinfectant or replacement of the filter 82, it is held in a removable tray that can easily be inserted in and removed from the case 1 1. Alternatively, a door or sliding access hatch could also be used to gain access to the tray holding the filter 82.
  • a gasket 86 prevents unfiltered air from passing through the cartridge since allowing unfiltered air through not only results in odorous emissions from - - the case 11 but also may result in the motor 22 being clogged by the particles found in the unfiltered air.
  • FIG. 3 shows an embodiment of the present invention provided with a case 100 enclosing another adjusting means 102 for adjusting the distance between a movable electrode 110 and a conductive plate 120.
  • Case 100 also surrounds and contains a power supply, which may be either a battery 12 or a transformer that may couple to a main power supply via a conventional plug and cord, a storage circuit 20 and a motor 130.
  • a power supply which may be either a battery 12 or a transformer that may couple to a main power supply via a conventional plug and cord, a storage circuit 20 and a motor 130.
  • the filtration system comprising a fan and a filtered cartridge may also be placed within the case 100).
  • Movement or vibration of the vibrating plate 120 ensures that slag 72 does not build up upon the surfaces of the vibrating plate 120 that acts as an electrode for conducting current to a needle tip inserted through a hole 101 in the case 100. for destruction. Vibration can be accomplished by mounting the high rpm motor 130 to the vibrating plate 120. Placing an eccentric weight 132 on the motor shaft causes the motor to vibrate and the vibration is mechanically transmitted to the vibrating plate 120. Vibration also may be accomplished by spring-loading vibrating plate 120, attaching a cam to a rotating shaft driven by the motor 130 and abutting a cam against one end of the plate 120. Rotation of the cam will translate into mechanical vibration of the spring-loaded vibrating plate 120.
